Looking for help with autocomplete working with mysql and php

Adobe removed the old fashioned server-behavior panels from DW CC.  As yet, they have not provided any replacement tools.   So you either code manually as I do with PHP and MySQLi (imporoved).

See connection example:

<?php
$con = mysqli_connect("localhost","your_username","your_password","database_name");

// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
		}
		else echo "Successfully connected, happy coding!"
?> 

Or, you may purchase 3rd party extensions from WebAssist or DMX Zone.

Alternatively, you may wish to use DW for site management and another product like Wappler for web app development.
